<p>A high pressure, non-pneumatic heat sealer that comprises of an electric motor, combined with a gear box and geared rack or worm drive to produce a linear drive unit 1 to create a strong linear motion. The device will preferably have a combination of compression springs 2 and flexible pack support 6, with an accurate reactive control mechanism switch 3 which provides continuous high pressure between the hot sealing plate 5 and the pack being sealed 7. The process control is provided by the timer and heater control unit 4. The innovation can thus heat seal packaging requiring a high pressure, controlled temperature and time duration, without the use of compressed air.</p> |
